Thrombosis of Bioprosthetic Valves
O ver the 5 decades that bioprosthetic valves (BPVs) have been commonly implanted, the frequency of superimposed thrombosis has been thought to be negligible (1). Thus, early echocardiographic follow-up of patients with BPVs has been sparse, and chronic anticoagulation was mostly avoided. After the baseline post-operative study, current guidelines state that “patients with bioprosthetic valves ...
متن کاملBioprosthetic valves and laudable inflammation?
from the University of Alberta (Canada) report a series of animal experiments designed to test the mythic role of gluteraldehyde in preventing recognition of bioprosthetic heart valve antigenicity with subsequent rejection and failure. Gluteraldehyde–cross-linked xenograft tissues (initially porcine) have been used in the manufacturing of stented (and now stentless) heart valves since 1970. Ori...
متن کاملSubclinical Valve Thrombosis in Sutureless Bioprosthetic Valves
I n the current issue of JAHA, Dal en et al 1 report the results of a single-center prospective observational study of 47 patients with implantation of the Perceval sutureless bioprosthesis (LivaNova, Milan, Italy). Cardiac computed tomography (CT) performed at a median of 491 days (range 36– 1247 days) found hypo-attenuated leaflet thickening (HALT) in 18 (38%) and reduced leaflet motion (RLM)...
متن کاملComparative hydrodynamic evaluation of bioprosthetic heart valves.
BACKGROUND AND AIM OF STUDY Pressure gradients across cardiac valve prostheses have been identified as one of the most important performance measures in valve replacement surgery. Specifically in aortic valves, these gradients influence reduction of left ventricular hypertrophy and are postulated to influence long-term survival. The correct choice of replacement valve is hampered by a lack of u...
متن کاملLong-term clinical evaluation of mitral valve replacement with porcine bioprosthetic valves in dogs.
This study evaluated the long-term clinical performance of newly developed porcine bioprosthetic valves cross-linked with glutaraldehyde and polyepoxy compound for mitral valve replacement (MVR) in dogs. Five beagle dogs underwent MVR using the porcine bioprosthetic valves during cardiopulmonary bypass. Antithrombotic drugs were administered only for one month after MVR. Six months after MVR, t...
